Engine Performance problem
2004 Hyundai Elantra 4 cyl Front Wheel Drive Automatic 87000 miles

I need to replace my o2 sensor. Looking at the front sensor I can clearly see there are 5 wires coming out of it. However, when I search various auto parts websites, most are selling o2 sensors with 4 wires and yet they claim that these are the correct items for my vehicle. Could these 4 wire sensors work and what is the difference? I have found some that sell 5 wire sensors but they are considerably more expensive. Is the difference worth it? I live and drive in AZ if that makes a difference. Thank you

Thanks, but actually the engine is not the SULEV type but a 2.0 L DOHC 16-Valve CVVT engine. In this case, would a 4 wire o2 sensor work?
I did speak to the dealer, but they said it was not covered.

Many people are fooled by the 10/100 myth. Here's the real info:

The Performance Warranty covers repairs which are required during
the first 2 years or 24,000 miles of vehicle use because the vehicle
failed an emission test. Specified major emission control components
are covered for the first 8 years or 80,000 miles.

Hello, this is old but I am in the same position except I already took out my old sensor which I will likely regret. The colors on the other side are two whites, light green, pink, brown, and yellow.

Thanks in advance
